Turaiel Posted July 2, 2012 Share Posted July 2, 2012 Good day everyone! I've got 10.7.2 running on my HP Pavilion dv7-4280us, but I'm having trouble getting proper graphics, wifi, and my internal microphone working. Graphics Issue (ATI Mobility Radeon 6550M / Intel HD3000) Currently it boots into OS X with the Intel graphics from my i5-480M, but without a kext, so I don't have QE/CI right now. Here's what I've gathered from the Internet so far, though I don't know how reliable the information is: Because this model has switchable graphics, the only way to enable the ATI card is by modding the BIOS (I'd prefer not to mod it though) My Intel graphics have a strange device id, compared with other models of HD 3000 graphics (0046:8086, rather than 01xx:8086), and it doesn't look like people have had a lot of luck with it. Even though the system is running on Intel graphics, the ATI card may still be powered on, causing excessive battery drain. Here's what I'd like to find out: Is there a way to disable Intel graphics and use the ATI card without modifying the BIOS? If not, how can I get QE/CI working on my Intel chip? If the ATI card is indeed still powered on, how can I turn it off? (I've heard through DSDT, but there isn't a DSDT that exists for my model) Wireless Issue (Broadcom BCM43224AG) My Broadcom wireless card (which is evidently the same model used in late model MacBook Pro/Air) doesn't seem to be working for me. I've read around and found that other people are having trouble with this model, but I haven't found a solution that's worked for me yet. I've read that people have modified the chip's firmware and even their BIOS, but I would really prefer to not do that (because I still have to use the card on Windows). Audio Issue (IDT High Definition Audio w/ Beats) My system has an integrated IDT audio card. I installed the VoodooHDA kext from http://www.osx86.net...p?do=file&id=22, and everything is working except for the microphone. When I updated to the latest VoodooHDA drivers, it caused the system to stop booting with the infamous "Still waiting for root device" error, so I had to roll back. The microphone in this model seems to be integrated with the webcam (which is working), so I don't know whether I can actually use it or not. Specs Summary System: HP Pavilion dv7-4280us OS X Version: 10.7.2 Processor: Intel Core i5-480M GPU: Intel HD 3000 / ATI Mobility Radeon 6550M Wireless: Broadcom BCM43224AG If anyone can help with any of these issues at all, it would be HUGELY appreciated.
